THREAD-FEEDING ATTACHMENT non snwme-ivmcnrnns.

Application filed August 21, 1914. 1 Serial No. 857,884.

To all whom it may concern: a Be it known that 1, CHARLES E. Harms, a citizen of the United Statesgresiding at Brockton, in the county of Plymouth and State of Massachusettshave invented certain new and useful Improvements in Thread-Feeding Attachments for Sewing Machines, of which the following is a specification. a l

- This invention relates to improvements in. sewing machine attachments and more par ticularly to thread feeding apparatus.

The object in view is' the increase'in the efiective feeding of the thread by subjecting the thread substantially at the point of supply to a resistance suflicient for tensioning the thread in the courseof being supplied to the needle.

With this and further objects in view, as will in part hereinafter become apparent and in part be stated, the invention comprises a movable spool carrier, and a bracket upstanding therefrom and having frictional guiding means for thread delivered from a spool sustained by the spool carrier.

The invention comprises certain other novel constructions, combinations and ar rangements of parts as will be hereinafter specified and claimed.

In the accompanying drawing: Figure 1 is a view in side elevation of a fragment of a sewing machine having applied thereto the apparatus embodying the features of the present invention. Fig. 2 is a similar view of the same detached, parts being broken away for the saving of space and parts being seen in vertical section. Fig. 3 is a vertical section taken on the plane indicated by the line 83 of Fig. 2, parts being seen in elevation.

Referring to the drawings by numerals, 1 indicates the usual arm of a sewing machine, from which upstands the spool sustaining spindle 2. The arm 1 and usual mechanism of the sewing machine is sustained on an ordinary table 3 on which is mounted a stand 4 which is preferably retained in place by securing means extending through an aperture & in the stand engaging the table.

I The stand 41 is formed with a'vertical passageway which registers with an aperture in the table and is adapted to receive a rod 5.-

The rod 5 is surrounded by a collar 6 which is locked in position on the'rod 5 by a set screw 7 so that the rod will be sustained upon the stand 4: and still free to revolve relative thereto. A set screw 8 is threaded through a portion of the stand 4 into engagement with the rod 5 for grippingthe rod and maintaining the same in a given adjusted position. The'rod 5 is bent to form an offset horizontal portion- 9 producing a bracket having an upstanding portion fixed to a disk or plate 10. The means of connection between the bracket and plate is susceptible of a wide range of variation but preferably consists of threads, therod being externally threaded and engaging internal threads of anaperture in the plate. Pref= erably the rod engages the plate centrally thereof,.and the plate at the central point is provided with an upstanding shank 11 Specification of Letters Patent. Patented Augzigl, 1915.

which is formed with a bore from beneath 1 for receiving the threaded end of the bracket rod. The shank 11 serves the useful purpose offorming a bearing for a spool or other thread container 12 rotatably resting ,A short shaft 18 extends I lnto the upper/end of the spool 12 and carupon plate 10.

ries a revolubly mounted disk 14 disposed above the upper end of the spool andprovided with a thread guiding aperture '15at one point, the disk being preferably formed with a thickened rounded portion 16 having a curved wall'appro'aching the aperture :15 for preventing the presentation of a sharp corner to a thread fed from the spool through the aperture 15.

A rod or arm 17 has its lower end fixed to plate 10 and extends upwardly to a point considerably above the plane of the upper end of the spool 12 and is bent thence to form an overhanging portion 18 having its free end approximately overhanging the central portion of spool 12. Rod 17 and the portion 18 are formed with guiding eyes or apertures 19, 19, and the thread from nism so that the approach of the thread to said mechanism is substantially the same as when thread is threaded from a spool carried by spindle 2, while the advantage of the thread is obtained. As the thread is being fed the disk 14 Will rev0lve"f0r' keeping the aperture nearest the point of discharge,
